T-Shirt Tシャツ

A cool cartoon stone character takes center stage against a deep black background, styled with long dark hair, a confident smirk, and a studded black jacket. The rough gray rock texture is softened by smooth shading and rounded edges, blending toughness with cute charm. Held across the body is a sleek electric guitar, adding a bold rock‑star vibe to the playful design. Strong outlines, muted tones, and expressive details turn this quirky character into a fun fusion of music attitude and whimsical illustration.
